3-8Positioning the camera with respect to the examined eye (alignment)
In fundus photography, it is necessary to guide an amount of exposure necessary for photography to the fundus through the
pupil. Therefore, the location of camera with respect to the examined eye is limited.
1 Set the illumination lamp intensity select knob of the power supply unit pointing at 10 o'clock (position of "K" as in
KOWA indicated along the periphery).
2 Adjust its position while looking at the examined eye from the side of the camera unit with the forehead being set
against the forehead rest such that the examined eye is about 5 mm away from the light projecting prism.
3 Looking at the examined eye from the side of the camera unit, make sure the illuminated image can be formed on the
cornea of the examined eye.
4 Looking into the ocular, fine-adjust the position of the camera unit with respect to the examined eye such that illumi-
nation light is uniformly guided into the fundus to prevent a formed image from getting out of focus.
NG In focus in the right-hand half

Because fundus camera is a precision instrument, picture quality may depend on how well your daily maintenance and
inspection have been conducted. To use the product properly and safely, it is recommendable to read these items carefully.
6-1Daily inspection
1) After photography is complete, be sure to turn OFF the power switch and replace the objective lens cap.
2) Care must be used to protect the objective lens and the light projecting prism against dust, fingerprints, teardrops and so
on.
Be sure to check objective lens and light projecting prism for any foul before starting photography for the day.
3) If fouled, clean camera unit, power supply unit and forehead rest with soft cloth. If stubbornly fouled, apply diluted neutral
detergent to them. If applied to them, chemical or solvent such as thinner and benzene will degrade, deform the objective
lens and light projecting prism or peel off their paint.
1 Wipe off their exterior with soft cloth which was moistened with water and whose moisture was then tightly squeezed
off.
2 Softly wipe off the LCD monitor screen with soft cloth like gauze because it is liable to suffer damage.
3 If stubbornly fouled, wipe it off with soft cloth which was moistened with neutral detergent diluted by water or luke-
warm water and whose moisture was then tightly squeezed off.
4) If there is no need to use the fundus camera for a long period of time, keep the power cable unplugged from the wall
outlet.
● If all of a sudden, the fundus camera that has been stored in a cool room should be moved to a warm room, the
objective lens or other internal lens .may be misted. In this case, allow some time for mist to disappear from them.
Otherwise, pictures taken may be out of focus.
● If lens is repeatedly misted, it may become moldy. In this case, contact your dealer where you purchased the
fundus camera for overhaul.
Do not wipe off the exterior of the fundus camera with solvent such as benzene, alcohol, thinner and ether
that may cause discoloration and deformation.
P - 32
Page 34
6-2Inspecting/cleaning objective lens and light projecting prism
A shadow of white maybe reflected to the same place of the picture when objective lens and light projecting prism were dirty
with the fingerprint. Clean a lens in the following procedure.
1 Lightly wipe in a circular motion the objective lens and light projecting prism from their center little by little to their outer
side using cotton swab slightly moistened with a mixture (1:1) of absolute alcohol and ether.
2 If even the dirt should resist the mixture, you may do the job by slightly wiping them around with a cotton swab slightly
moistened this time with water.
After going through these steps, thoroughly wipe them again with this mixture. For stubborn dirt still existing on them,
contact your dealer where you purchased the fundus camera.
● If the objective lens should be wiped hard with dust depositing on it, it may suffer damage.
● Do not use chamois leather or silicone cloth.
● Be very careful about handling the mixture because it is liable to evaporate or catch fire.
6-3Cleaning/disinfecting the forehead rest
Every time photography is complete for one patient, lightly wipe the forehead rest with soft cloth slightly moistened with ether
beforehand for photography of another patient to come.
